If that's the case, you're better off sticking to a weightlifting routine or sport-specific with longer rest intervals. You wouldn't be able to perform well on a meter sprint with only 60 seconds of rest between rounds. But for both weight loss and improving endurance or conditioning, Donavanik says the ratio is ideal, and you can progress to the ratio.
For example, start with 30 seconds of work with a second rest, then increase to 40 seconds of work with a second rest. And the rest periods need to be long enough that your breathing is back under control before you jump back into the work interval.
You can't rest too long, however, as you need your heart rate to stay up. While there's no one "ideal interval time" that works for everyone and every workout, the guide below based on the input of our experts will provide some work-to-rest ratios that can help when planning your workouts:.
And remember to keep your rest periods on the shorter side. Donavanik says 30 to 60 seconds of rest is ideal for weight loss or general conditioning, but he doesn't recommend going above 90 seconds. Also, take into account the type of activity you are doing. For example, jumping lunges or high knees will require longer rest times than squats or crunches. In general, though, listen to your body and adjust your intervals accordingly.
Rated as the No. Follow these three HIIT tips to take your workouts to the next level, and make consistent body composition and strength improvements. Overuse injuries can arise if workouts are too long; cap HIIT workouts at 30 minutes. But instead of putting together a minute, non-stop workout, break up your program into shorter all-out intervals with brief recovery periods.
For example, three workouts of minutes each with a short recovery between each one will allow for a higher level of intensity, and keep you from getting bored doing the same movements over and over again. I saw the same effect when I entered a metabolic chamber to measure my metabolism. In the periods after I hit the exercise bike, my metabolic rate ramped up — but only by a few more calories each minute, and the effect wore off within half an hour of exercising.
Building more muscles, however, can be a little more helpful for the afterburn. At any given weight, the more muscle on your body, and the less fat, the higher your metabolic rate. But that takes work — a lot more work than a short aerobic HIIT workout. And even a short HIIT workout may not be for everyone.
